Bank Frauds, Cyber Safety and Customer Liability: RBI Rules
Exam notes on bank fraud and cyber safety: zero and limited liability rules, reporting windows, liability table, Central Fraud Registry and ombudsman.
By GK24 Editorial Team· Published · 5 min read

As banking moved from the branch counter to the mobile phone, fraud moved with it. A fraudster no longer needs to forge a signature; a stolen one-time password is enough. The Reserve Bank of India has answered this with a set of rules that decide, in plain numbers, how much of the loss a customer must bear when money leaves an account without permission. Those rules are among the most practical things in the whole banking awareness syllabus, and they are asked repeatedly in IBPS, SBI, RBI and SSC papers because the figures are exact and easy to set a question on.
How bank fraud happens
Frauds fall into two broad families. The old family is paper based: forged cheques, altered instruments, impersonation at the counter, loan fraud through fake documents and inflated valuations, and internal fraud by staff. The new family is digital and depends on getting the customer to part with a credential, or on cloning the instrument.
- Phishing: a fake e-mail or website that looks like the bank's and collects the customer's login details.
- Vishing and smishing: the same trick through a voice call or an SMS, often with a caller pretending to be from the bank and asking for a one-time password to stop a block.
- Skimming and card cloning: a device fitted to an ATM or a point of sale machine copies the magnetic stripe and a hidden camera records the PIN.
- SIM swap: the fraudster gets a duplicate SIM for the customer's number so that the one-time password reaches the fraudster.
- UPI and QR code fraud: the victim is asked to scan a code or approve a collect request to receive money, when the action actually sends money out.
- Money mules: ordinary accounts, often opened for a small payment, used to move the proceeds of fraud so the trail breaks.
The rule that matters: limited liability of the customer
The Reserve Bank's circular of 6 July 2017 on customer protection in unauthorised electronic banking transactions fixed how the loss is shared. Three principles run through it. First, the burden of proving that the customer is liable rests on the bank, not on the customer. Second, how much the customer bears depends mainly on how quickly the fraud is reported after the bank's own message about the transaction. Third, the bank must put the money back quickly and ask questions later.
The customer bears nothing at all in two situations: where the fraud, negligence or deficiency is on the part of the bank, whether or not the customer reports it; and where the fault lies elsewhere in the system, a third-party breach, and the customer reports it within three working days of receiving the bank's communication.
Where there is a third-party breach but the customer takes four to seven working days to report it, liability is limited to the transaction value or the amount in the table below, whichever is lower.
| Type of account | Maximum liability of the customer |
|---|---|
| Basic Savings Bank Deposit accounts | Rupees 5,000 |
| Other savings accounts, prepaid payment instruments and gift cards, current or overdraft accounts of micro and small enterprises, individual current or overdraft accounts with limit up to 25 lakh rupees, credit cards with limit up to 5 lakh rupees | Rupees 10,000 |
| Other current, cash credit and overdraft accounts, and credit cards with limit above 5 lakh rupees | Rupees 25,000 |
If the report comes after seven working days, the liability is decided by the bank's own board-approved policy. Where the loss is due to the customer's own negligence, such as sharing the PIN, password or one-time password, the customer bears the entire loss until the fraud is reported; every rupee lost after the report is the bank's liability. Working days are counted as per the home branch's schedule, leaving out the day the bank's message was received.
Timelines the bank must keep
- A shadow reversal, that is a credit of the disputed amount to the customer's account, within ten working days of the customer's notification, without waiting for any insurance claim to be settled.
- Resolution of the complaint and determination of the customer's liability within the period in the bank's board-approved policy, and in any case not more than ninety days from the date of the complaint.
- A twenty-four hour channel, through SMS, e-mail, a toll-free helpline and the website or app, for reporting an unauthorised transaction, with an acknowledgement to the customer.
How frauds are recorded and investigated
Banks report frauds to the Reserve Bank, which maintains the Central Fraud Registry, a searchable database available to banks so that a borrower or an entity already involved in fraud at one bank can be checked before credit is sanctioned elsewhere. Large frauds are referred to the police or the central investigating agencies. The Reserve Bank's Master Directions on fraud risk management require a bank, before it classifies an account as fraud, to give the borrower a notice and a chance to be heard; this follows the Supreme Court's decision in the State Bank of India versus Rajesh Agarwal case of 2023, which held that the principles of natural justice apply to such a classification because it carries serious civil consequences.
Cyber safety habits and where to complain
A customer protects an account mainly by never sharing a one-time password, PIN, CVV or password with anyone, including a caller claiming to be from the bank, by not clicking on links in unexpected messages, by using only the official app, and by keeping SMS and e-mail alerts switched on so that an unauthorised debit is noticed within the three-day window. Card details stored with merchants are replaced by tokens so that the real card number is never kept by the shop. For cheques, the Positive Pay System asks the issuer to confirm the details of a high value cheque, of fifty thousand rupees and above, before it is paid. A financial cyber fraud should be reported at once on the national cybercrime helpline 1930 and the National Cyber Crime Reporting Portal of the Ministry of Home Affairs, since a report in the first hours makes it possible to freeze the money downstream. If the bank does not resolve a complaint within thirty days, the customer can approach the Reserve Bank's ombudsman free of cost under the Reserve Bank Integrated Ombudsman Scheme of 2021, which replaced the three earlier schemes with a single one nation one ombudsman arrangement and a central receipt and processing centre.
Exam Point of View
The numbers are the question. Learn the three day window for zero liability, the four to seven day window for limited liability, the three liability figures of 5,000, 10,000 and 25,000 rupees with the account types attached to each, the ten working day shadow reversal and the ninety day resolution limit. Conceptual questions ask who bears the loss when the customer shared the OTP, and on whom the burden of proof lies. From the institutional side expect the Central Fraud Registry, the Integrated Ombudsman Scheme of 2021, the cyber fraud helpline 1930 and the sections of the Information Technology Act on identity theft and cheating by personation. The traps are swapping the 5,000 and 10,000 rupee rows, reading the three day and seven day windows as calendar days instead of working days, counting the day the bank's message arrived, and assuming the customer always loses everything after sharing an OTP, when losses after the report are the bank's.

Practice MCQs on this topic
In a case of third-party breach, within how many working days must a customer report an unauthorised electronic banking transaction to have zero liability?
- A.One working day
- B.Three working days
- C.Seven working days
- D.Fifteen working days
Show answer
Explanation
The correct answer is B, three working days. Under the Reserve Bank's circular of 6 July 2017, where the fault lies neither with the bank nor with the customer but somewhere else in the system, the customer's liability is nil if the unauthorised transaction is reported within three working days of receiving the bank's communication about it. The day on which that communication was received is excluded from the count, and working days follow the home branch's schedule.
Option A, one working day, is stricter than the rule and would leave many genuine victims uncovered. Option C, seven working days, is the outer edge of the limited liability window, where the customer does bear a capped amount, so it is the most attractive wrong answer. Option D, fifteen working days, has no place in the framework; a report after seven working days is dealt with under the bank's own board-approved policy. Fix the pair in mind: three days for zero liability, four to seven days for capped liability.
For a Basic Savings Bank Deposit account, what is the maximum liability of a customer who reports a third-party breach between four and seven working days?
- A.Rupees 5,000
- B.Rupees 10,000
- C.Rupees 25,000
- D.Nil in all cases
Show answer
Explanation
The correct answer is A, rupees 5,000. The Reserve Bank's liability table sets the lowest ceiling for Basic Savings Bank Deposit accounts, which are the no-frills accounts opened for financial inclusion, because their holders are the least able to absorb a loss. The customer pays the transaction value or five thousand rupees, whichever is lower, so a fraud of two thousand rupees costs the customer two thousand, not five.
Option B, rupees 10,000, is the ceiling for ordinary savings accounts, prepaid payment instruments and gift cards, current or overdraft accounts of micro and small enterprises, individual current accounts with a limit up to twenty five lakh rupees, and credit cards with a limit up to five lakh rupees. Option C, rupees 25,000, is the ceiling for other current, cash credit and overdraft accounts and for credit cards with a limit above five lakh rupees. Option D is wrong because zero liability needs a report within three working days.
Within how many working days of a customer's notification must a bank make a shadow reversal of the disputed amount?
- A.Three working days
- B.Seven working days
- C.Ten working days
- D.Thirty working days
Show answer
Explanation
The correct answer is C, ten working days. A shadow reversal is a provisional credit of the disputed amount into the customer's account. The circular requires the bank to make it within ten working days of the customer's notification, and specifically says the bank may not wait for any insurance claim of its own to be settled first. The idea is that the customer should not be out of pocket while the investigation runs.
Option A, three working days, is the reporting window for zero liability, not a bank deadline. Option B, seven working days, is the end of the limited liability window for the customer. Option D, thirty working days, is close to the thirty day period after which an unresolved complaint can be taken to the Reserve Bank's ombudsman, but it is not the shadow reversal deadline. Keep three timelines apart: three days and seven days for the customer, ten working days for the shadow reversal and ninety days for final resolution.
A bank must resolve a complaint of an unauthorised electronic transaction and determine the customer's liability within a maximum of:
- A.30 days from the complaint
- B.60 days from the complaint
- C.90 days from the complaint
- D.180 days from the complaint
Show answer
Explanation
The correct answer is C, 90 days from the complaint. The circular requires every bank to have a board-approved policy fixing its own resolution period, and caps that period at ninety days from the date the complaint is received. If the bank cannot complete the exercise within ninety days, it must still compensate the customer as the circular prescribes, so delay does not work in the bank's favour.
Option A, 30 days, is the period after which a complaint not resolved by the bank can be taken to the Reserve Bank's ombudsman, which is a different deadline and a common source of confusion. Option B, 60 days, does not appear in this framework. Option D, 180 days, is far longer than the rule allows. Pairing helps: ten working days for the provisional credit, ninety days for the final decision, and thirty days of bank inaction before the ombudsman can be approached.
In a dispute about an unauthorised electronic banking transaction, on whom does the burden of proving the customer's liability lie?
- A.On the customer
- B.On the bank
- C.On the police
- D.On the payment system operator
Show answer
Explanation
The correct answer is B, on the bank. The circular places the burden of proof squarely on the bank: if a bank says the customer is liable, it must establish that, rather than asking the customer to prove innocence. This matters because the bank holds the logs, the device records and the transaction trail, while the customer holds almost nothing, so putting the burden on the customer would make the protection meaningless.
Option A is the intuitive but wrong answer, and banks sometimes behave as though it were true, which is why the question is set. Option C is wrong because the police investigate the criminal offence; liability between the bank and its customer is a civil matter settled under the Reserve Bank's rules. Option D is wrong because a payment system operator such as a card network or the retail payments organisation is not a party to the customer's account relationship for this purpose.
If a customer loses money because he shared his one-time password with a caller, how is the loss shared?
- A.The bank bears the entire loss
- B.The customer bears the entire loss, before and after reporting
- C.The customer bears the loss till reporting; the bank bears the loss after reporting
- D.The loss is shared equally in all cases
Show answer
Explanation
The correct answer is C, the customer bears the loss till reporting and the bank bears the loss after reporting. Sharing a PIN, password or one-time password is treated as customer negligence, and in that case the circular makes the customer bear the whole loss up to the time the fraud is reported. The moment the report is made, the bank is on the hook for every further rupee, because it is then the bank's job to block the account and the instrument.
Option A is wrong because a customer who hands over a credential cannot pass the whole loss to the bank. Option B is the harsher reading that many candidates choose, but it ignores the second half of the rule and is the main trap in this question. Option D is wrong because the framework never prescribes an automatic equal split; liability depends on who was at fault and on how quickly the report came. The practical lesson is to report at once even when the mistake was one's own.
Under the RBI's liability table, a credit card with a limit above five lakh rupees attracts a maximum customer liability of:
- A.Rupees 5,000
- B.Rupees 10,000
- C.Rupees 25,000
- D.Rupees 50,000
Show answer
Explanation
The correct answer is C, rupees 25,000. The highest ceiling in the table applies to other current, cash credit and overdraft accounts and to credit cards whose limit exceeds five lakh rupees. The logic of the table is that the bigger the account, the greater the amount a customer is expected to watch over, so the cap rises with the size of the facility.
Option A, rupees 5,000, applies only to Basic Savings Bank Deposit accounts. Option B, rupees 10,000, applies to ordinary savings accounts, prepaid payment instruments and gift cards, micro and small enterprise current accounts, individual current accounts with limits up to twenty five lakh rupees, and credit cards with limits up to five lakh rupees, so the five lakh limit is the dividing line between the ten thousand and twenty five thousand rows. Option D, rupees 50,000, does not appear anywhere in the table and is a pure distractor.
The Central Fraud Registry, a searchable database of frauds reported by banks, is maintained by:
- A.The Central Bureau of Investigation
- B.The Reserve Bank of India
- C.The Securities and Exchange Board of India
- D.The Indian Banks Association
Show answer
Explanation
The correct answer is B, the Reserve Bank of India. Banks report frauds to the Reserve Bank, which keeps them in the Central Fraud Registry and makes the database searchable by banks. A lender can therefore check whether a borrower, promoter or firm is already linked to a fraud elsewhere before sanctioning credit, which closes the gap that allowed a defaulter to move from one bank to the next.
Option A, the Central Bureau of Investigation, investigates large frauds referred to it but does not maintain this registry. Option C, the Securities and Exchange Board of India, regulates securities markets and keeps its own records of market offences, not bank frauds. Option D, the Indian Banks Association, is an industry body and issues common guidance for banks but has no such statutory database. Along with the Central Fraud Registry, remember the Central Repository of Information on Large Credits, which tracks large exposures rather than frauds.
Which is the national helpline number for reporting financial cyber fraud in India?
- A.1091
- B.1930
- C.14448
- D.1800
Show answer
Explanation
The correct answer is B, 1930. The number is run under the national cybercrime reporting arrangement of the Ministry of Home Affairs and is meant for the immediate reporting of financial cyber fraud, alongside the National Cyber Crime Reporting Portal. A call in the first hours lets the amount be traced and frozen in the accounts to which it has been transferred, which is why speed matters more here than paperwork.
Option A, 1091, is the women's helpline and is unrelated. Option C, 14448, is the Reserve Bank's own number for its ombudsman and consumer education arrangement, used for a complaint against a bank rather than for reporting a crime, which makes it a good distractor. Option D, 1800, is only the prefix used by toll-free numbers in India and is not a helpline by itself. Remember 1930 for cyber fraud and 14448 for the banking ombudsman.
Cheating by personation using a computer resource is punishable under which section of the Information Technology Act, 2000?
- A.Section 43
- B.Section 66C
- C.Section 66D
- D.Section 72
Show answer
Explanation
The correct answer is C, Section 66D. This section punishes a person who, by means of any communication device or computer resource, cheats by personation, which is exactly what a phishing website or a caller pretending to be a bank officer does. It is the provision most often invoked in online banking fraud cases, along with the general cheating provisions of the criminal law.
Option A, Section 43, provides for compensation for damage to a computer or computer system and is a civil remedy rather than a criminal punishment. Option B, Section 66C, deals with identity theft, that is the dishonest use of another person's electronic signature, password or unique identification feature; it is closely related and is the main alternative that candidates pick. Option D, Section 72, punishes breach of confidentiality and privacy by a person who has secured access to records under the Act. Learn 66C for identity theft and 66D for cheating by personation.
The Positive Pay System introduced by the Reserve Bank of India applies to cheques of what value and above?
- A.Rupees 10,000
- B.Rupees 50,000
- C.Rupees 2 lakh
- D.Rupees 5 lakh
Show answer
Explanation
The correct answer is B, rupees 50,000. Under the Positive Pay System the issuer of a high value cheque sends the bank the key details, such as date, beneficiary name and amount, through a channel like the mobile app or internet banking, and the paying bank matches those details before honouring the cheque. The system covers cheques of fifty thousand rupees and above, which is where cheque tampering is worth a fraudster's effort.
Option A, rupees 10,000, is below the threshold and would cover almost every cheque, defeating the purpose of focusing on high value instruments. Option C, rupees 2 lakh, does not appear in the arrangement. Option D, rupees 5 lakh, is the value from which banks may make the facility compulsory for their customers rather than optional, so it is a half-right answer and the main trap here. Remember fifty thousand as the coverage threshold and five lakh as the level at which a bank may insist on it.
Under which scheme can a bank customer approach the Reserve Bank of India free of cost if the bank does not resolve a complaint within thirty days?
- A.The Banking Codes and Standards Scheme
- B.The Reserve Bank Integrated Ombudsman Scheme, 2021
- C.The Deposit Insurance Scheme
- D.The Consumer Welfare Fund Scheme
Show answer
Explanation
The correct answer is B, the Reserve Bank Integrated Ombudsman Scheme, 2021. The scheme merged the separate ombudsman schemes for banks, for non-banking financial companies and for digital transactions into a single one nation one ombudsman arrangement, with a centralised centre to receive and process complaints in any language. A complaint costs the customer nothing, and it can be filed once the bank has failed to resolve the matter within thirty days or has rejected it.
Option A refers to the voluntary codes of fair treatment that banks commit to, which are not a redress forum of this kind. Option C, the deposit insurance scheme run by the Deposit Insurance and Credit Guarantee Corporation, protects deposits up to a prescribed limit if a bank fails, an entirely different purpose. Option D is not a Reserve Bank scheme for banking complaints. The ombudsman is the step after the bank's internal grievance machinery, not a substitute for it.
Frequently Asked Questions
If money is debited from my account without permission, how soon must I report it to bear no loss?
In the case of a third-party breach, if you report the unauthorised transaction within three working days of receiving the bank's communication about it, your liability is zero and the bank must refund the whole amount. If the loss happened because of the bank's own fraud, negligence or deficiency, your liability is zero whether or not you report it.
What is the maximum I can lose if I report after four days?
For a third-party breach reported in four to seven working days, your liability is the transaction value or the ceiling for your account type, whichever is lower. The ceiling is five thousand rupees for a Basic Savings Bank Deposit account, ten thousand rupees for other savings accounts, prepaid instruments and credit cards with a limit up to five lakh rupees, and twenty five thousand rupees for other current accounts and bigger credit cards.
What happens if I shared my OTP with a caller?
That is treated as customer negligence, so you bear the entire loss up to the moment you report the fraud. Everything lost after you report it is the bank's liability. This is why reporting immediately matters even when the mistake was yours, and why the bank is required to keep a twenty-four hour reporting channel open.
What is a shadow reversal?
It is the provisional credit of the disputed amount into the customer's account. The Reserve Bank requires the bank to do this within ten working days of the customer's notification, without waiting for any insurance claim to be settled. The final liability is worked out later, within ninety days of the complaint, and adjusted against this credit.
Where should I report a financial cyber fraud?
Inform your bank at once through its twenty-four hour channel, and report the fraud on the national cybercrime helpline 1930 and the National Cyber Crime Reporting Portal of the Ministry of Home Affairs. Reporting in the first hours allows the money to be frozen in the accounts it has been moved to. If the bank does not resolve the complaint in thirty days, approach the Reserve Bank's ombudsman, which costs nothing.
What is the Central Fraud Registry?
It is a searchable database maintained by the Reserve Bank of India in which frauds reported by banks are recorded. Banks consult it before sanctioning credit, so that a borrower, promoter or entity already linked to a fraud at one bank does not quietly obtain a loan from another. It works alongside the fraud reporting returns banks file with the Reserve Bank.
